Features | Solution | Application | Why Choose Drawell | Feedbacks | Other Products
The gas chromatograph is a Chromatography that uses chromatographic separation technology and detection technology to perform qualitative and quantitative analyses of complex multi-component mixtures. There are many types of gas chromatographs with different functions, but their basic structures are similar.
Principle: Separation of mixtures based on differences in boiling points, polarity, and column.
Components: A gas chromatograph is generally composed of carrier gas system, sample introduction system, separation system, temperature control system, detector.

Different Application Solution of Gas Chromatograph
- Gas testing
What are the components (all) in the gas to be tested?
What is the approximate content?
Which components need to be tested?
If your sample is gas, please let us know the answer, then we can recommend suitable configuration.
- Determination of ethanol content in ethanol disinfectants
Ethanol disinfectant refers to a disinfectant made mainly of ethanol as raw material, in which the ethanol content is usually detected by gas chromatography.
- Determination of chloroform(CHCl3) and carbon tetrachloride(CCl4) in water
- Determination of organochlorine pesticides
Organochlorine pesticides are organic compounds containing organochlorine elements in their components used to control plant diseases and insect pests. They are mainly divided into two categories: those using benzene as raw material and those using cyclopentadiene as raw material.
- Determination of aromatics content in gasoline
Benzene is a recognized carcinogen. Although it contributes a lot to the octane number of gasoline, it is harmful to the human body when it is discharged into the atmosphere due to incomplete evaporation and combustion. Therefore, from the perspective of environmental protection, it is necessary to limit the benzene content in gasoline.
Please contact staff for specific applications and configuration recommendations.
Applications of Gas Chromatograph
1. Environmental protection: analysis, monitoring, and research of trace toxicants in polluted places such as atmospheric water sources.
2. Biochemistry: clinical application, pathological and toxicological research.
3. Food analysis: analysis and research of trace components in microbial beverages.
4. Chinese and Western medicine: analysis of raw material intermediates and finished products.
5. Petroleum processing: analysis and control of petrochemical industry, petroleum geology, oil composition, and ore control research.
6. Fine chemical analysis: additive analysis, catalyst analysis, raw material analysis, and product quality control.
7. Pesticide residue analysis: organochlorine pesticide residue analysis, pesticide residue analysis, herbicide residue analysis, etc.
